Nuts are $97.50 for 6 pounds. If you bought 8 pounds, how much would it cost?

Answer 1

First we need to find how much 1 pound costs in units $/pound

$97.50 / 6 pounds = $16.25 per pound

Then since we know how much 1 pound costs, we multiply by 8 to find out how much 8 pounds cost:

$16.25 * 8 = $130.00

Side Note: The above equation's units would be ($ / pound) * (pound) and the pounds would cancel out to give just $
